I added the following line to /etc/network/interfaces
auto ens7iface ens7 inet static address 192.168.1.2 netmask 255.255.255.0
when I do systemctl restart networking I get
Job for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.
I am trying to add a internal IP address to my ubuntu 16.04 VPS
